The COOKOO watch uses a two battery system--one battery powers the Connected Display while a separate battery powers the watch's analog movement.
The battery for theConnected Display is designed to last up to one year when in standby mode. However, actual battery life will vary greatly with use and depends on both the number and frequency of notifications you receive as well as the number of disconnect and reconnect events you experience with your COOKOO watch.
The battery for the analog movement is independent of the connected system and is designed to last up to three years.
The battery for the Connected Display is easily replaceable. Click here to learn about changing the battery in your watch.
